TYPEWRITING-MACHINE.

Specification of Letters Patent.

Patented Feb. 17, 1920.

Application filed Kay 29, 1918. Serial No. 237,215.

To all whom it may concern:

' Be it known that I, ALFRED G. F. KU- ROWSKI, a subject of the Emperor of Germany, but having taken out preliminary United States naturalization papers, residing in Brooklyn borough, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Typewriting-Machines, of which the following is a specification.

My invention relates to tabulating mechanism, and particularly to that type usually employed in the Underwood typewriter machine, in which adjustable stops carried by a rack adjacent the carriage of the machine determine the positions of columns typed upon the paper; said rack being usually operated by. a key to carry the stops into the path of '2. lug on the carriage, so that the carriage will be arrested in proper position.

In tabulating mechanism of the general type or kind above referred to, the tabulator stops, which determine the positions of the columns, are commonly located back of and below the carriage of the machine, and the setting of the stops is therefore amatter of inconvenience, as the operator has to reach over and down back of the carriage to get at the tabulating mechanism.

The principal feature of my invention is the provision of tabulating mechanism in which the tabulator stops and scale are car ried by an auxiliary supporting member or frame movable with the rack above referred to, and which auxiliary supporting member is movable in such a Way as to bring the tabulator stops and scale'into accessible positions, so that the stops may be readily set; suitable means being provided for locking the parts when the tabulating mechanism is' in its operative position.

Other features and advantages will hereinafter appear. I

In the accompanying drawings,

Figure 1 is a frontview illustrating my improved tabulator stop'mechanism in the position into which it is" moved when the stops are to be set, together with so much of a typewriting machine as is necessary in order to show its application thereto.

Fig. 2 is a similar view, showing the de vice and machine in end elevation, with the movable stop-carrying member swung down and locked in operative position.

Fig. 3 is a rear View showing certain details of construction of my invention.

Referring to the drawings, the reference numeral 5 designates an oscillating shaft or rod located adjacent the carriage and extending longitudinally of the typewriting machine shown conventionally in the several views, and the ends of which are pivotally supported in the frame of the machine -at 6, the said rod being operated through an arm 7 carried thereby and by means of a vertically-movable operating member 8 pivotally connected with the free end of the arm 7 at 9; the said operating member being operated by suitable tabulating keys in or disposed adjacent the keyboard of the machine. The bar or shaft 5 carries also an arm 10 the free end of which is operatively connected with a lever 11 pivotally supported at 12, and the free end of which lever carries a roller 13 which runs in engagement with the pivotally-supported rack 14, which rack in turn engages thepinion 15 rotating with the ratchet 16. of the escapement mechanism; whereby, as the operating member 8 is moved downward and an angular movement imparted to the rod 5, the rack 14 will be moved upward and out of engagement with the pinion 15, thus permitting the rack and the carriage which carries the same to move freely longitudinally of the machine and under the influence of its operating spring or other device provided for moving it, until its onward movement is arrested by the engagement of a lug 17 carried by the carriage with a stop carried by the tabulator stopcarrying device or mechanism to which my invention relates, as will hereinafter appear.

The mechanism for releasing the carriage is illustrated in a more or less conventional manner, and the form thereof referred to is for illustrative purposes only and for the purpose of disclosing the relation between my invention and the tabulating mechanism of a typewriting machine; my invention as disclosed and claimed in this present application bein in no Way concerned with the particular orm of mechanism employed to effect the release of the carriage as a step or operation involved in the use of the tabulating mechanism.

The oscillating shaft or bar 5' carries two arms 18 located one at each end thereof, and which arms partake of the angular movement of the shaft; the bar and arms forming a movablesupporting member adapted to support a tabulating stop and to move the same into and out of the path of movement of the lug 17, as above explained. The arms 18 in turn carry and serve as a support for a swinging tabulator-stop-carrying member or frame, the same being pivotally connected with the upper ends of the arms 18, at 19, and thus movable relatively to the movable supporting member formed by the rod 5 andthe arms 18.

carriage, thus arresting the movement of the The stop-carrying-frame or member may bevariously constructed, according to the choice of the manufacturer, having in view the matters of convenience in manufacture and low cost; but, as illustrated, the same comprises a longitudinally-extending bar 20, and laterally-extending arms 21 located one at each end thereof and the free ends of which arms are connected by a longitudinally-extending bar or rod 22 which servesas a support for and along which the tabu-' lator stops 23, as many being employed as may be deemed necessary or desirable, are movable, in order to secure the proper and desired location of the columns of figures;

upon the printed sheet, as will be appre ciated.

The reference numeral 24 designates a rack extending longitudinally of the tabu:

- lator-stop-carrying frame and the ends of which are secured to the side arms 21 thereof, and 25 designates a graduated scale carried by the said frame and secured to the rack 24 in the embodiment of my invention illustrated, which scale is graduated to correspond with the main line-spacing scale of the machine and is used by the operator in setting the stops to determine the proper location of the columns, as will be understood. Thev ta'bulator stops 23 are shown as provided each with a pointer 26; and they are movable angularly upon the supporting bar or rod 22 whereby they are carried, in order that a tooth 27 provided at the free end of each may be swung out of engagement with the rack 24, preparatory to moving the stop along the rod; the rack and tooth 27 serving as means for locking the stop in whatever position it may be placed. The stops 23 are also provided each with a lug '28 which, when the tabulating mechanism is operated to effect the stopping of the carriage in proper position for printing in. a column, are moved into and i p are engaged by the lug 17 carried by the the said lug 28 being moved into carriage;

of the lug 17 by means of 'a tabuthe path frame is locked in its lowermost position by e in the path of and V .and arms 18 carried thereby; and which arms in turn are connected with and support the stop-carrying-fram'e'carried by and movable relatively to the supporting member formed by the bar 5 and arms 18, as will be understood.

The swinging tabulatorstop carryingany suitable locking means, such,- for example, as the spring-operated catch or latch 29 pivotally connected with an arm 30 extend.- ing from one of the side arms 21 of the said frame, which latch engages a tooth 31 upon the adjacent arm 18 carried by the oscillating bar 5; the upward swinging movement of the said frame is arrested by contact be tween a projecting lug or pin 32 also carried by an arm 21, and an arm 18 and the tabulator stop mechanism'as a wholeis kept in its rearward and inoperative positionjwith the lugs 28 of the stops 2-3 out of" the ;-pathof travel of the lug 17 upon the carriage by means of a spring33 secured to and carried bv the bar5, and the free end of which contacts with the frame of the machine.

The movable frame member 21, whereby the rack 24 and bar 22, which carries the adjustable stops 23, are supported, is'illustrated as in the form of a casting, in which the transverse bar 20 and arms 21 are operation and one involving considerable inconvenience, and an operation which, because of the circumstances enumerated, is liable to be improperly performed, unless careful attention is glven to the matter.

In my improved tahulating mechanism, however, when the operator has occasion to, set the tabula-tor stops the latch or catch 29 is 'operated to release the swinging stopcarrying frame; whereupon the same, and the stops carried thereby may be swung into the elevated position in which the parts are illustrated in full lines in Fig. land in dotted lines in Fig. 2; thus bringing the tabulator stops and the scale for indicating their positions into plain sight, and into a position just back of and slightly above the carriage of the typewriter; in which position the adjusting of the stops can be readily done with the least inconvenienceand liability of error; after which the stop carrying member or frame is swung down and into its operative position, and locked therein by the latch as will be appreciated, the latch being swimg to effective position by the spring 35 coiledabout its mounting.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
